• Figure 6 shows the flattened and pierced end of the tube 2.
• FIGS. 7a and 7b show the use of a hinge pin 5, one of the elements 5b is secured to the end of the bar BE and the other element 5c secured to the part 6, or even, suitably bent, replacing part 6.
• FIG. 8 shows two tubes 1 and 2 and a coil spring 3 exerting its action on the free ends of the two tubes, a secondary tube 12 guiding the spring 3 internally when it is not guided externally by the tube 2.
• the overlap of the tube 2 by the tube 1 is at least equal to 10% of the length of 2 to ensure lateral resistance in the support bar.

These rooms are delimited by a part 10 closing the tube 2 and a sealed ring 13 integral with said tube 2 and in which the tube 12 slides.
• FIG. 11 has as an extension means 3 an independent pneumatic spring 17 housed in one of the tubes 1 or 2 and exerting its action on the end of the other.
• the embodiment of Figure 12 shows a coil spring 3 exerting a traction between the end 15 of a tube 12 sliding in the tube 2 and a ring 13 integral with the tube 2 and in which the tube 12 slides, this pulling action causing the bar to extend.
• the embodiment of FIG. 13 shows rectangular tubes 1 and 2 and a jack 17 parallel to the extension means 3 and of action opposite to that of this extension means.
• a protective tube 18, linked to the tube 2 by the shaft 5 and partially covering the tube 1 is terminated at a bevel 18a and is split longitudinally in 18b to easily deform and peel off from the tube 1 in the event of frost.

• the extension bar can be shortened remotely under the effect of a compressed fluid.
• the fluid is brought through a hole 5 21 a of the tube 12 into a chamber 16 of the tube 2.

• the pressurized fluid is brought by the tube 12 into the chamber 16b through an orifice 21a of the said tube 12, through the tube 22 and a valve 23 calibrated at P4 pressure.
• This fluid passes into the chamber 16a thanks to the functional leak of the piston 14 then is directed towards the outside, for example through the piston 14 and a tube c 24 located in the tube 12, and through a valve 25 calibrated to the pressure P1 lower than P4.
• the spring exerts an extension action between the tubes 1 and 2, the surface of the active section of 16a being greater than that of 16b.
• CEME _ If a fluid is introduced into 16b at a sufficient pressure, and with a flow sufficient to compensate for the functional losses of the piston 14, the overpressure at 16b becomes such that the piston 14 is pushed back towards the chamber 16a, and causes the shortening of the extension bar.
